Reset button text via Javascript

Well, I do not know if my title is related to what I'm asking for, but I have a form with an Enter button.

<button id="btn_entrar" data-loading-text="carregando..." autocomplete="off" class="btn btn-primary btn-cons m-t-10" type="submit" onclick="return Get_Acesso();">Entrar</button>

And when I enter login and password I want this button to be "loading ..." I searched the internet and saw this case:

  $('button[data-loading-text]').on('click', function () {
    var btn = $(this)
    btn.button('loading')
    setInterval(function () {
        btn.button('reset')
    }, 3000)
});

But I do not want a definite time (in the case 3 seconds) I want it to reset after my function GetAcesso() give some return is false or true. Does anyone know a solution?

function Get_Acesso(){
    usuario = document.getElementById('txt_user_name').value;
    senha = document.getElementById('txt_password').value;

    LoginDTO.Usuario = usuario;
    LoginDTO.Senha = senha;

    var DTO = { 'LoginDTO': LoginDTO};
    //acessar login
    $.ajax({
        type: "POST",
        url: "default.aspx/Acesso_Login",
        data: JSON.stringify(DTO),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        beforeSend: function () { 
            $('#btn_entrar').html('Carregando...');
        },          
        success: function (msg) {
            $('#btn_entrar').html('Entrar');
            try {
                //tratamentos de msg
                if (msg.d == "err") {
                    document.getElementById('spn_retorno').innerHTML = "Erro inesperado no momento do acesso.";
                    return false;
                    //Não encontrou nenhum registro
                } else if (msg.d == "not") {
                    document.getElementById('spn_retorno').innerHTML = "Usuário / senha inválido.";
                    return false;
                    //Campos vazios
        }

Simple access code, but I want it to return when the error returns with the default "Enter" button.

One option would be to make the request via ajax, so you would call the reset function after the response. Not knowing what this GetAcesso function is like, I imagine the best way to do it would be like this:

$.ajax({
    //Os seus parametros para verificar o usuario e senha
        data: parametros,
    //sera usado o método get
        method : 'get',
    //a url que queremos requisitar
        url    : 'requisitada.html',
    //o tipo da requisição
        dataType: 'html',
    //aqui é onde pegamos o retono da requisição
        success : function(retorno){
    //Aqui você coloca a função de resetar o texto do botão.
            ResetaTexto();
        }
    });

It was just an example to have at least one base. I think it's the best way.

Before success: function (msg) you can put one:

beforeSend: function(){ // Ou seja, 'antes de enviar'
    $('#btn_entrar').html('Carregando...');
},
success: function(msg){
    $('#btn_entrar').html('Entrar'); // Volta o botão no seu valor normal
}
